An introduction to sound waves with illustrations and explanations. Includes examples of simple wave forms. ... Sound waves exist as variations of pressure in a medium such as air. ...
Pressure waves propagated through air or other plastic media. Sound waves are generally audible to the human ear if the frequency is between approximately 20 and 20,000 vibrations per second.
Sound is vibration transmitted through a solid, liquid, or gas; particularly, sound means those vibrations composed of frequencies capable of being detected by ears. Perception of sound For humans, hearing is limited to frequencies between about 20 Hz and 20,000 Hz (20 kHz), with the upper limit...
